Systems and Methods for Providing Documents Based on Document Identifiers

1. A method for providing a copy of a document, comprising: storing or uploading at least one of a plurality of documents in at least one of a plurality of document repositories; collecting a plurality of document identifiers on a first medium; receiving and storing in a memory on a second medium the plurality of collected document identifiers, and a user identifier identifying a unique user; associating each document identifier with at least one of the plurality of documents stored in at least one of the plurality of document repositories, the document repositories different from the first and second media; linking the second medium with at least one of the document repositories; identifying a stored document as an identified document if any of the document identifiers correspond to a document stored in the document repositories linked to the second medium; and copying the identified document to a third medium.

2. The method of claim 1 , further comprising: receiving on the second medium an address identifier associated with the user identifier; and delivering the identified document to an address indicated by the address identifier.

3. The method of claim 2 , wherein the address identifier is in a form of a printed code, and receiving the address identifier comprises scanning the address identifier from the printed code.

4. The method of claim 3 , wherein scanning the address identifier comprises scanning the address identifier from an event registration badge.

5. The method of claim 2 , wherein the address identifier is in a form of a radio frequency identification, and receiving the address identifier comprises receiving the radio frequency identification.

6. The method of claim 1 , further comprising: collecting the document identifier based on a display of a copy of a printed or digital document, wherein the copy of the printed or digital document is displayed on a fourth medium, the fourth medium different from the first, second and third media.

7. The method of claim 1 , wherein collecting the document identifier comprises scanning or sensing the document identifier.

8. The method of claim 1 , wherein the document identifier is in a form of a data glyph contained on a business card, and collecting the document identifier comprises reading the data glyph from the business card.

9. The method of claim 1 , wherein the document identifier is in a form of a bar code, and collecting the document identifier comprises scanning the bar code.

10. The method of claim 1 , wherein the document identifier is in a form of an infrared data association, and collecting the document identifier comprises transferring the infrared data association from a portable device.

11. The method of claim 10 , wherein the portable device is one of a personal data assistant, a cellular phone, a notebook computer, or a pocket personal computer.

12. The method of claim 1 , wherein the document identifier is in a form of a smart badge, and collecting the document identifier comprises sensing the document identifier from the smart badge.

13. The method of claim 1 , wherein the document identifier is in a form of a token, and collecting the document identifier comprises collecting the document identifier from the token.

14. The method of claim 1 , wherein the document identifier is in a form of radio frequency identification, and collecting the document identifier comprises receiving the radio frequency identification.

15. A system for providing a copy of a document, comprising: a database storing document digital data sets associated with document identifiers; a medium that collects a plurality of document identifiers; a document identifier receiving circuit, routine or application that receives and stores in a memory the collected document identifiers, a user identifier identifying a unique user, the document identifiers associated with at least one of a plurality of documents stored in or uploaded to at least one of a plurality of document repositories, at least one of the document repositories being linked to the document identifier receiving circuit, a delivery information receiving circuit, routine or application that receives delivery information from at least one of the document repositories, the user information comprising the delivery information; a document identifier matching circuit, routine or application that identifies a document digital data set from among the stored document digital data sets which is associated with each document identifier stored in the document identifier receiving circuit as an identified document if any of the document identifiers correspond to any of the plurality of documents stored in the document repositories linked to the document identifier receiving circuit; and one or more of (a) an output device that outputs a copy of the identified document, and (b) a delivery address associating circuit, routine or application that associates the identified document digital data set to a delivery address based on the delivery information for delivering a copy of the identified document to the delivery address.

16. The system of claim 15 , wherein the document identifier is carried on a first medium that is distinct from a second medium on which the document identifier receiving circuit, routine or application is provided.
